Match each kind of drug to the effect it has on the brain.

A stimulant accelerates bodily functions while slowing down brain activity. An inhalant breaks down fatty tissues in the brain. Steroids affect moods within the limbic system.

Answer 1 B) Inhalant ⇔ Dissolves the fatty tissue in the brain. Inhalants encompass a broad range of home and industrial chemicals whose vapors or pressurized gases are inhaled for a euphoric effect, often in ways not intended by the manufacturers. Such products include propane tanks, butane lighters, and various refrigerants. Nitrites are often classified as a separate category of inhalants. Answer 2 A) Steroid ⇔ Influences moods in the limbic system. A steroid is a biologically active natural compound with a specific four-ring structure. Steroids play two important roles in physiology: they are critical components of cell membranes affecting their fluidity and act as signaling molecules. Answer 3 C) Stimulant ⇔ Speeds up body functions but depresses brain activity. Stimulants, commonly referred to as uppers, temporarily enhance alertness and energy. Frequently abused drugs in this category include cocaine and amphetamines, while prescription varieties come in pill or capsule forms.
